I think it bizarre that we expect politicians to 'believe' in things befre they can deliver them. TM was I think a Remain person but when the vote was in, she took on the PM role and is busy trying to deliver what the public voted for. It would be healthier I am sure, if we chose people who could act upon the brief we give them rather than trying to get people who are belivers themselves.
I remember years a go a very successful clergyman told me he wasn't required to belive in any of it, just to provide the services and pastoral comfort that his flock wanted.
We expect other professionas to get on and do the job they are tasked with, barristers don't have to believe in their client, nurses dont have to accept that patients did all they could to keep well, they sign up for the work and they get on with it.
If we chose people for their qualities as planners, orators, administrators, negotiators etc and then told them what we wanted we might do better. We are verging upon residential or cult followers at the moment which I find disconcerting.
People seem to think that JC stands for Jesus Christ, including the man himself, we are not Americans!!!!!
